    Design Failure But a Real Bargain!Very poor design when compared to past B&D Spacemakers. The model I replaced truly fit UNDER the cabinet. This one must protrude at least two inches from the face of the cabinet in order to accommodate the blade lever lifting to a vertical position for removal. The old one could be set truly under the counter/cabinet and folded up into the housing instead of having a cover. If the blade lever design did not require a vertical position beyond the housing itself, the cover could still close UNDER the cabinet. The old design used a blade release for removal. I also fear that that “push to release” cover mechanism is just another ‘designed to fail’ feature to assure future sales soon after the warranty expires. I, too, also miss the magnet lifting the lid out of the way. I was also disappointed that I could not simply attach this one to the same holes I had used for my old one. I now have eight holes instead of just four. All the instructions clearly say for installation only on a flat bottom cabinet type and not for those with an overhang or a top lip. Well what’s the matter with B&D designers? They obviously considered those issues but did not design around them. I was lucky, I had a flat bottom on my microwave shelf. My old one broke because the plastic on engagement lever broke and I had to press on the blade mechanism itself to engage the motor. This one eliminates the engagement lever and that is good, but all in all there was nothing wrong with the old design except that the product was relatively durable and probably reduced repeat sales. I used the old one more than 15 years in at least 3 different homes.I used to respect B&D but this is not the only time I’ve been disappointed in their redesign efforts.Addendum: I just looked at some of the other Spacemakers listed on Amazon. The unit I replaced was an EC600 shown on Amazon for $239.99. There is no way that I paid any more than $40.00 15 or 20 years ago This model is CO100B, the black version. Model CO100 is on sale at Amazon for $226.00. It is the white version, well worth an additional $191.00, right? The CO95, I guess an earlier version, offers no additional features, except it won’t open tall cans because this cover does not swing all the way down, It is for sale for a whooping $499.00 from one seller. He must have quite an inflated view of profit margin! The PEC90, Spacemaker PLUS is only $99.00. I think the plus is for the knife sharpener. The CO85BM handsome black brushed metal version is only $249.00, It doesn’t have a bag opener or cover and does not foldaway. The EC700 Slimline, a foldaway version, is only $289.00, I could go on but the conclusion I reach is that by comparison, this is a real bargain and I upgrade it to four stars.I think B&D ought to look into pricing disparities. Others actually bought at those inflated prices what is offered here at about $35.

    Guess I lived too long.I purchased this one because of the reliability of B & D like electric can opener about 15 years ago that finally gave out as did my ex-wife with the identical mortality rate. The first one was totally reliable and lasted far longer than I would ever expect. It fit perfectly under a kitchen cabinet away from the sink, stove etc. The new one; A. Had additional features – bottle cap opener (to my knowledge few of any bottles have cap lids anymore) rather screw off type or tab pulls. I guess it is a selling feature but does me no good. B. This model also has a bag opener. It took me 20+ minutes just to locate it and still don’t know how it operates as I haven’t any bags to open. If I do, I pull out a knife or the pair of kitchen shears and Wa-La it is open. With this added feature to the opener, to access it you have to down open a really neat cover and then wrestle around with a plastic bag, I guess like a frozen bag of vegetables, get it just in the right position wedging your hand between the cabinet it is mounted to and the cold plastic bag you are trying to open at the same time. But, again yet another “selling feature” you can tell your neighbors about, maybe they’ll buy one too. It does come with excellent mounting instructions for being positioned under a kitchen cabinet. What nothing in the on-line advertisement Amazon had did it say anything about “will not fit on cabinets with any type of lip overhang as mine. Of course the first place you find that out is in the mounting instructions you received with the opener. At that time, “Hey Honey, I got you a new electric can opener.” With my luck naturally, the previous mounting holes in the bottom of the cabinet did not align with the new opener. Now the underside looks like a piece of Swiss cheese. However, you cannot see it, and it was no trouble to mount it even with a overhanging lip on the cabinet. I love the neat little fold down cover and as far as opening cans, I would rate it among the best. Those other “Great” features really are not. I am willing to bet it will be totally dependable and last just as long as its predecessor (and regardless longer than me.) Thus, it will be the last electric can opener I ever buy, but certainly not due to any flaw in the product.

    Better Quality Than Expected, Easy MountingAt first, I wasn’t sure what to expect from this Space Maker can opener, and honestly my expectations weren’t that high. But, that was only because the price of this thing was just a fraction of other under-cabinet can openers. I expected cheap construction and low-quality parts.So far, however, I’ve been pleasantly surprised. This can opener installed without a problem, and my cabinets have a 3/4″ overhang. I didn’t have to attach any wood, or build any kind of spacer contraption either, like other people described. Instead, I just used two of the included plastic spacers that came in the package. There were several sizes, so I used the 1/2″ spacer together with the 1/4″ spacer and it worked perfectly. I’ll attach a photo so you can see exactly what it looks like.The paper template that came in the box was a huge help figuring out exactly where to drill the holes. Honestly, without that template I probably would have drilled a dozen holes in my cabinet and still not gotten it right…As for functionality, it does just what it’s supposed to – it opens cans. If you’ve ever owned any other electric can opener, you won’t have a problem using this one. Also, the bag opener works well for bags of pretzels, potato chips, Doritos, etc. Other types of bags don’t do so well, though. The bottle opener works fine, too. Nothing fancy or unusual there.The knife sharpener seems to work well enough, but all of my kitchen knives are already pretty sharp so I can’t really tell yet if it’s doing a good job. One piece of advice, though, is to use the sharpener slowly to avoid scratching the edges of the unit. Pull the knife straight out, rather than at a downward angle, or else the blade will be cutting the trim as you pull it through.Overall, I’m happy with this can opener unit so far. It looks good and does its job. If it lasts more than a year, I’ll be ecstatic. I’m attaching some pictures to show you what it looks like installed and how I used the spacers to mount it to a cabinet with a 3/4″ overhang.

    I Love This Can Opener!I love this little can opener! I have had it for a couple of months now and use it almost daily.The mounting instructions are very easy to follow. You will need a drill, drill bits, and a screw driver to install it.I have read where people are having trouble with the spacers. I had no trouble at all. It may be because I have fairly updated cabinets. I have about 1/2 to 3/4 of an inch drop to the rail of my cabinets, and the spacers included worked perfect to make this can opener line up perfectly with the bottom of the cabinet rail.It opens cans with ease. I’ve had no trouble opening small (tomato paste) cans, typical (15.5 oz) cans, are the much larger cans. This hold them up and opens them with no problems.My girlfriend loves the fact that you can close the “lid’ on this can opener so it leaves a slick look in the kitchen when not in use (which, let’s face it…it’s not in use like 99.99999999999999999% of the time.) I had considered just taking the “lid” off, but she won’t let me. Ugh, she’s got me trained!The power cord is long enough to reach the nearest outlet in most kitchens. The bottle opener works just fine and doesn’t adjust the can opener’s position (meaning it doesn’t slide from side to side when applying pressure to the can opener.) The knife sharpener I’ve used once, just so I could write a comprehensive review, and it worked just fine.Let’s face it, most mountable can openers are very expensive (in the neighborhood of $100+.) So purchasing this one was a no-brainer, and it works with absolutely no flaws! Score one for the consumer!Long story shorts, I would recommend this product to friends and family

    Very Poor Design But Works After ModificationsThe design is really terrible on this can opener. It’s really made for cabinets without a recess under them. In every house I’ve ever lived in, the cabinets have a deep recess under them so I can’t even picture what cabinets would look like that this would work with.To be fair, there are some stackable spacers that can be used to fill that gap at the rear, but the mounting holes for the front screws are so close to the front of the unit that you would have to drill downward through the fascia of the cabinet. I really didn’t want to be drilling in that!. Oh, just mount the opener farther back you say? Nope, that’s impossible because the cutter can’t be be tilted high enough to get a can in place because it would bump into the cabinet.I cut a piece of wood that had a little lip so I could mount the can opener to it and then used wood screws to go through the cabinet bottom to the wood mount. With that piece in place, everything works as expected.The can opener works fine. I mean, it opens cans with no problems. I haven’t had the problem that others have where it won’t stay in the cutting position without holding the handle of the cutter down manually. Mine works just fine, automatically.As far as the knife sharpener goes, I have good knives, so I’m always hesitant to try out sharpeners like the one here, but I tried it on a cheaper knife and was actually surprised at how well it worked. It seems to be a ceramic sharpener, not a grindstone like I’ve seen on other models. I like the bottle opener and it works well, however you need space under the unit to use it. I haven’t used the bag opener, so I can’t comment on how well that works.Would I buy this again in the future? If this one lasts more than five years and there is no other model on the market that fits better, then I would buy it again especially since I have my wood block to make mounting easier.

    Works great. To my surpriseI bought this to replace the almost 15 year old automatic can opener my fiance managed to break. Shipping was quick, as is expected from Amazon, and packaging did not leave me wondering whether the product would work. When I opened the amazon box, I found the can opener in retail packaging with added more piece of mind to the fact that it would work. It came with instructions that doubled as a template for where to drill holes into the cabinet. Roughing out the location where the opener would fit with enough room to allow the front cover to open and close, I taped up the drilling template and went to town. I think the most difficult part was running the bolts from inside the cabinet to the unit and ensuring the plastic spacers that were included didn’t slide out of alignment while trying to bolt it to the cabinet. It has a variety of spacers and bolts of different lengths for maximum adaptability to your cabinets. After struggling with installation and eventually enlisting a second set of hands, we got it installed and gave it a go. Works great. To my surprise, it has other features built in like bottle openers and a little thing to cut packaging open, not that any of it is in a convenient location for regular use, but hey, it’s there. Would recommend to a friend in need.

    Perfect replacement for an 25+ year old B&D under cabinet can openerPerfect replacement for a 25+ year old B&D under cabinet can opener. I was worried about the way this would hang under the cabinet, size, look, etc.Fear not! This looks great, easy to operate, has al the parts necessary to be mounted under a cabinet that has a bottom recessed, or not. In my case the bottom of my cabinet is recessed over 1″ and I used all 16 spacers (four for each of the four long screws). They provided 12 machine screws, 3 lengths of 4 each. Sixteen spacers, each set of 4 are different lengths and are designed to be stackable and 4 plastic tapered washers to make the screw heads in the cabinets clean looking and less of an issue. They did not provide a mounting template, however, you can easily create one by placing a piece of paper over the opener and threading 4 screws into the screw holes. This creates the hole pattern. Then just place the template on the inside of the cabinet shelf to mark where the holes need to be drilled.My old opener used three screws and I was only able to reuse one pre-drilled hole as the old and new units do not have the same hole pattern.The time involved to clear the cabinet shelf, gather tools (drill, drill bit, flathead screwdriver for the old screws, Philips screwdriver for the new holes and a pencil), uninstall the old unit, install the new unit, clean up the wood shavings and restock the shelf was about 20 minutes in total.New opener works better than the old version, looks better and appears “visually” to be smaller

    It makes the product stick out more than I would like from under the counterThe cover is a push open, push again to close (not a latch type closure) which may or may not last very long. It is tight to open all the way and I thought I was going to break it if I opened it enough to open a large can. The can opener is bulky compared to the one I previously had and the one’s my mother has had but most of it fits under the counter so you don’t notice. My problem with this is the cover. It makes the product stick out more than I would like from under the counter. You can remove the cover. That leaves the problem of the leaver sticking out as it does not push down to be flush with the can opener. Either way, you (meaning me) will have to adjust slightly to the extra distance from the counter and getting items out of the cabinet. But for the price (most of these simple can openers, which used to be around the same price are now over $125) it’s seems to be a good product. I have only opened 1 can and it seems to operate smoothly-no loud motor noise.

    Mount it right the first time, or do it again!Seems to be a good unit, although I haven’t had it long enough to expound on its reliability.I replaced another Black & Decker (circa 2012) under cabinet can opener. The old one has a slight chip off from the tip of the cutter blade (that opens a can). A couple of points:- in some installations, there is a slight (1/2″ or so) indent behind the visible lower edges of cabinets, you’ll need to account for this to allow easy operation of the can opener- make a spacer from appropriate thickness plywood or suitable board, I created mine using a couple pieces of flooring laminate (3/8″ thick) by laying their supplied template on the flooring board and drilling holes. Best to drill the holes using 1/4″ bit, as the screws go THROUGH the holes (not screw into them), they should have a bit of slop to account for imperfect location/layout 🙂 This will result in a much sturdier mount than the spacers they give you – in my case, I thought it would be simple can-opener swap-out, being that they are both Black & Decker. Haha, never assume! Mounting hole locations are different, so new holes are required, in both underside of cabinet and the spacer(s)

    Best can opener ever! Long lasting.This was one of the first purchases for our new house that we bought in 2017. My wife uses it daily. After 3 years it still works perfectly. I use the bottle opener frequently as well. It’s extremely convenient.My only real complaint is with the knife sharpener. It’s awful. It has ruined and chipped the edge of any knife I’ve tried sharpening with it. And the placement of It makes it awkward to use anyways. The sharpener is complete garbage and I’d be happier if weren’t there at all.Overall, very happy with it, very highly recommend it. And definitely will purchase again when/if we wear ours out.
